Would love to hear comments on the 2 Willwood kits. 6 piston caliper upgrade for the rear and the kit including the 4 piston caliper upgrade front and rear including 12.19 x 1.25 rotors. You can PM if you prefer.
#6018 is equipped with older Wilwood "Superlite" brakes. The disks are 1-1/4" thick (racing disks). These expensive brakes are part of the reason why I chose to purchase this car.
The disks are the same diameter at all four corners. The calipers have 4 pistons at all four corners. The pads are the same dimensions at all four corners. There's no proportioning valve. The braking has been balanced by varying the front & rear caliper piston diameters. The front pistons are 1-3/4 inch diameter, the rear pistons are 1-3/8 inch diameter. The calipers are mounted towards the middle of the car; front calipers are mounted behind the axle, the rear calipers are mounted in front of the axle.
#6018 brakes with no nose dive or tail lift, that's at any speed including triple digits. And it brakes hard, stops in very short distances! 12.19 inch disks with 4 piston calipers were standard equipment of the Group 4 Panteras, and were once standard equipment on Indy Racing cars too … they have all the stopping power your street Pantera needs.
